Rapid sedimentation system for clarification of sugar juice

Abstract

The invention discloses a rapid sedimentation system for clarification of sugar juice. The rapid sedimentation system comprises a settler, wherein one side of the settler is provided with a feeding chamber, the settler is connected with a flash tank through a connecting pipe, the flash tank is used for carrying out flash evaporation and gas dissipation on the sugar juice and is installed above the settler, the connecting pipe is in a U shape so as to keep the flash tank and the settler work at the same liquid level, the connecting pipe is provided with a flocculating agent adding pipe, the feeding chamber is used for uniformly stirring and mixing the sugar juice and a flocculating agent and then overflowing the mixture into the settler, and the settler is used for quickly settling precipitate particles formed after a flocculation reaction of the sugar juice, so that solid-liquid separation of clarification treatment is quickly completed, and clear juice and mud juice materials meeting the requirements of the subsequent production process of the sugar factory are formed. According to the invention, the sedimentation efficiency can be improved, the color value of clear juice is reduced, the sugar loss is reduced, and the requirements of high-yield, high-quality and high-recovery development of cane sugar factories are met.

Description

technical field [0001] The invention belongs to the technical field of sugarcane sugar-making equipment, in particular to a rapid sedimentation system for sugar juice clarification. Background technique [0002] Most sugarcane sugar factories in my country use the sulfite method to clarify the sugar juice to produce white granulated sugar. Lime, sulfur dioxide, phosphoric acid and flocculant are used as clarifiers. These precipitated particles and other dispersed particles are suspended and dispersed in the sugar juice, and must be treated with solid-liquid separation to obtain clean clear juice. Due to the good settling effect, the settling equipment commonly used in sulfitic sugar factories is the TDJ type continuous settler with multi-layer settling structure. However, due to the low settling efficiency of the equipment, the residence time of sugar juice in the equipment is at least 1.5 hours. If the time is too long, the color value of the clear juice will be high, and t...

Due to the good settling effect, the settling equipment commonly used in sulfitic sugar factories is the TDJ type continuous settler with multi-layer settling structure. However, due to the low settling efficiency of the equipment, the residence time of sugar juice in the equipment is at least 1.5 hours. If the time is too long, the color value of the clear juice will be high, and the loss of sugar will be too much; the equipment is bulky and heavy, the work is unstable, and it is easy to "turn the bottom". Developmental needs to reduce sugar loss
